Abstract

Demonstrated here is a unique, and previously unreported, template-assisted polymerization pattern transfer method for the tailor-made fabrication of ultra-high-aspect-ratio (up to 1600:1) nanostructures (nanopillars) integrated into polymer-based MEMS devices. UHARN pillars are readily surface modified with proteins and aptamers via resist-free patterning methods to afford enzyme reactors and protein capture beds with unprecedented surface-to-volume ratios (from 1 × 104 cm-1 to up to 6 × 104 cm-1 versus ∼500 for open channels), resulting in rapid enzyme consumption of substrates and high efficiency capture of target analytes.
